SPECIFICATION forming part of Letters Patent No. 483,410, datedSeptember 27, 1892.

Application filed January 14:, 1892. Serial No. 418,061. (No model.)

To all whom t may concern:

Be it knoWn that LDAVID H. WATTS, acitizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented certainImprovements in Portable Grates, of which the following is aspecification.

The object of my invention is to so construct a portable grate for openfireplaces that it can be readily adj usted to tit fireplace-openings ofdiii'erent dimensions. This object I attain in the following manner,reference being had to the accompanying drawings, in Which-- Figure l isa perspective View of my improved adjustable grate. Fig. 2 is a planView showing the grate adjusted to an opening or niche. Fig. 3 is afaceView of the grate. Fig. 4 is a rear view of the grate. Fig. 5 is a viewof a detail of my invention, and Fig. 6 is a sectional plan view of thegrate.

Portable open grates as usually made are of one size and are generallymuch smaller than the fireplace-opening. Consequently it is difficult tomake the coal burn properly in the grate, as the air has atendency topass up at each side of the grate rather than through the body of thefuel, and Where a grate is made to t an opening it is generally built inand is not a portable grate.

By my improvement I am enabled to make a grate of one size, which can beeither eX- tended or contracted, so as to accurately fit anyV of theordinary fireplace-openings.

A is the front of the grate, made of three sections c a a2. In thepresent instance the end sections a 0.2 have hollow bars c3, into whichextend the ends of the bars forming the section c, so that when thefront A is contracted these sections telescope, as will be clearlyunderstood by referring to Fig. 2.

B is the back of the grate, formed of a central section b and sidesections b h2. In each side section are slots h3, through Which pass thebolts h4, as clearly shown in Fig. 4E. These bolts in the presentinstance are tapped into the central section l). Secured to the centralsections a and h of the front and back plates is the central iixedgrate-frame C, having eX- tensions c at each side, forming bars, and acentral pivot-section c', having trunnions c2, adapted to the sockets inthe central frame C. This section is commonly called the dumpingsection, and is common to all grates.

Thesections b b2 of the back section B slide in the recessed portion h5of the central section l?, (shown in Fig. 4,) so that the back section,although sufficiently loose to be contracted or expanded, will beperfectly rigid against any lateral or vertical motion.

D D are the side plates of the grate, connected to the front section Aby hinges d d and to the back sectionB by hinges d', so that while theyconnect the front and back sections together they allow one section tobe extended a greater distance than the other, so as to adapt the grateto the fireplace openings or niches of different shapes.

On the inner portion of the sections a c2 of the front plate are pocketse, in which rest the rounded ends of grate-bars E, and on the inner edgeof the sections h b2 of the back plate are pockets e for the receptionof the opposite ends of the grate-bars E. These grate-bars are on aplane below the gratebars c, so as to allow the grate to be contracted,the gratebars E passing under the grate bars c.

The grate-bars E are in the present instance loose, and simply rest inthe pockets c e. Thus the grate-bars do not interfere with the movementof either the back or front sections.

I attach in some instances to the front section a draft-regulator F,made up of three sections f f f2. The central section is adapted togrooves g g', formed in the side lsections ff2, and is provided with adamper h, by Which the draft through the iire is regulated. On each endsection is a hook vl, adapted to openings e" in the leg portions of thefront plate A. These hooks are inserted into openings i2 and drop intothe portion z" of the opening, thus locking the draft-regulator to thegrate.

It will be understood that while I have shown the bars of the frontplate square in cross-section they may be round or of other shapes,depending upon the style of ornamentation of the grate.

It will be seen that a grate constructed in accordance with my inventioncan be fitted to different-sized replacebpenings and to replace-openings in which the j ambs are tapered, as shown by full lines in Fig. 2, or

and grate only need be adjustable, and in some cases the back of theopening may be of a regular size and the front of the opening may be ofdifferent Widths. In this case the front plate only need be adjustable;but I prefer to make both plates adjustable in order to meet alldemands.

Having thus described my invention, I claim and desire to secure byLetters Patent- 1. The combination, in a portable grate, of thelongitudinal plates formingthe front and back of the grate andgrate-bars with side plates hinged to the longitudinal plates, one ofsaid longitudinal plates being adjustable, substantially as set forth.

2. The combination of the adjustable front section, the adjustable backsection, and adj ustable grates With side plates hinged to the front andback sections, substantially as described.

3. The combination ofthe telescoping front section, the telescoping backsection, side plates hinged to the front and back sections, a centraliixed grate, pockets on the front and back sections, with grate-barsadapted to the said pockets, substantially as described.

4. The combination, in a portable grate, of

the front plate made up ot three setions, the i A. W. HELLER, J. W.GRIFFIN.
